The entire mainline of the N15 has 19-inch radius curves. This means that trains of long cars look at home on it, and trains of short cars look even better.

Since the branch has sharp turns which tend to give it a different flavor from the mainline, there are many possibilities for additional industry tracks when you get around to it.
